Reduce verification work
Verification is a slow and expensive process. ABBYY FlexiCapture provides automatic validation rules that validate documents without an operator, so manual verification can be skipped. Another way to reduce verification work is to clarify with the customer which document fields have to be extracted with 100% quality. Often this is not every field. Verification can then focus only on the documents with problems in those fields.Estimate the number of verification operators
To calculate the number of verification operators, you need to know:- The number of documents to be processed
- How many of those documents require verification
- The time available to process a document, according to the Service Level Agreement
- The average time needed to verify one document
How verification loads the System
Verifiers also generate a workload on the System. A Verification Station interacts with the Application Server in much the same way as a Processing Station. It requests tasks, downloads images and document data from the Application Server, and sends the modified data back. Two things make that load different from a Processing Station:- The processing speed of a Verification Station is much slower, because manual verification takes far longer than automatic processing.
- Verification operators do not always need document images in their original quality. The FlexiCapture settings let you change the compression of images that operators download from the Application Server. The default is 60%.
Convert operators to processing cores
Assume that one verification operator working at full capacity generates up to 1/5 of the load of one processing core on a Processing Station. Use that ratio to interpret a test run in unattended processing mode, without verification operators. Suppose a System with 100 processing cores is stable. You can then safely replace N of those cores with N × 5 simultaneous verification operators.Worked example
A customer needs to process 100,000 documents in 8 working hours. Before going live, create a test batch from typical documents and test the System in unattended processing mode.- 30% of the documents require manual verification, and each takes up to 2 minutes, so up to 125 verifiers are required.
- Each document has about 3 pages on average, so the System processes about 300,000 pages.
- The test shows the System is stable at 100 processing cores, and 60 processing cores are already enough for 300,000 pages in 8 hours.
- 125 verifiers are equivalent to at most 25 processing cores, so the System handles 125 verifiers working alongside 60 processing cores.
